STOP MECHANISIVL To all whom it may concern:

Be it known that I, JAMES A. BROGAN, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain Improvements in Stop Mechanisms, of which the following description, in connection with the accompanying drawings, isa specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to stop mechanisms, andis illustrated as embodied in a machine for winding hanks of welting or other stock. In so far as thereis common subject-matter, the present application is in part a continuation of my prior application Serial No. 231,205, filed April 27, 1918, upon which was granted United States Letters Patent No. 1,412,837, dated April 18, 1922.

In winding hanks of welting, or other stock, whichcomes in lengths which are relatively short as compared to yarn or thread such as is handled by most winding and reeling machines, it is important that the winding machine stop automatically when the end of each length is reached. Accordingly the present invention has for .an object the;provisi0n in such a winding machine of means for stopping it automatically when the end of each length of welting or other stock is reached.

ll iththis object in view, one feature of the invention is to be found in a novel organization of a member engaging the strip of stock with connections for stopping the actuating mechanism of the machine when the end of the strip runs out from under said member. As illustrated, a spring is utilized to trip a lock or detent unless prevented by resistance of the stock; upon passage of the end of the strip of stock, there fore, the detent is tripped, actuating connections which throw out a clutch,thereby stopping the machine.

This and other features of theinvention, including specific constructions and combinations otparts, will beapparent from the following description of one embodiment of my invention illustrated in the accompanying drawings, in which:

end elevation showing the detent and the slide which carries it; and

Fig. 6 is a view similar to Fig. 5 but showing a modified form of slide.

As explained in my above-identified prior application, the winding machine illus trated in the accompanying drawings c0mprises generally a reel 10, rotated alternately in opposite directions on shaft 12 by straps l4 operated by cranks 16, driven by shaft 18 carrying a pulley 20. The cranks, shaft, and pulley are enclosed in a casing 22. Pulley 20 is rotated by a belt 24; passing over guide pulleys 26 and drive pulley 28, which supplies power to the machine.

Co-operating with reel 10 to lay the strip or w-elting, or other stock, in figure 8 convolutions about the arms of the reel, is a reciprocating guide throat 80, on a slide 32 which is movedby a pitman actuated by a lever 36 rocked by crank 38. The welting is kept taut bya spring take-up me1nber d0, which acts upon the welting between the guide throat 30 and a roll 42 over which the welting is passed. The operation ofthe foregoing parts is explainedin, and covered by the claims of, my prior application, and no extended discussion is deemed necessary herein.

According to the aspect of the invention covered by the present application, pulley 28 forms one member 01 a clutch, carrying a pin 50 (Fig. 1), arranged to be engaged by the inner end of a pin 52 passing through a clutch disk 5%. Disk 5a is looselymounted on the hub of an axially-movable powerdriven pulley 56, to which it is secured by a spring 58. Thus when pulley 56 is moved axially to a position where pin 52 engages pin 50, power is yieldingly transmitted from pulley 56 through spring 58 to clutch disk 54, and thence by means of pins 50 and 52 to pulley 28 which drives the machine. This prevents ars in starting the operationof the machine. To prevent undue tension of spring 58, pin 52 extends through disk 54 and the outer end of said pin projects between two spokes ot' pulley 56, which engage it if there is too great relative angular movement of disk 54 with respectto pulley 56.

Pulley 56 is rotatablymounted on a slide rod 60 passing through bearing 62 about which pulley 28 rotates, the pulley 56 being restrained as shown from sliding movement on the rod. The opposite end of rod 60 is flattened (Fig. at), and carries a pin 64 running in a cam slot 66 (Fig. 3) in disk 68, which is turned to reciprocate rod 60 to stop and start the machine.

Disk 68 is mounted on a rock shaft 70, arranged to be turned by lever 7 2 havinga pin and slot connection with a slide 74:, which is formed with slots 76 engaging pins 7 8 on a stationary support 80 carried by casing 22. By this arrangement, vertical reciprocation of slide 74 acts through the above-described mechanism to stop and start the machine.

In order that the position of slide 74 may be controlled automatically by the work, a detent or lock member 82 is pivotally mounted on slide 74, to engage a lug 84 on support 80 when the slide is in its uppermost position. lVhen a strip of stock is in the machine, one side of it engages a roller 86 on support 80 (Fig. 1), and the other side is engaged by a roller 88 carried by one arm of detent 82 and arranged to guide the strip. The rollers 86 and 88- are further arranged so that the detent can not be tripped to clear lug 841- until the passing of the end of the strip from between the two rollers allows roller 88 to be rocked toward roller 86 by spring 90 carried by lug 92 on detent 82-, and engaging support 80. When this does take place, however, slide 7 L drops and the abovedescribed stop mechanism is actuated.

In order that slide 74: may be raised to start the machine when a fresh strip of welting or other stock has been supplied, detent 82 is carried on a handle 94, by which it may be moved laterally, against the resistance of spring 96, to clear lug 84.

According to the modification shown in Fig. 6, the stop mechanism may be thrown out to allow the machine to operate continuously if desired, by turning handle 98 to bring hook 100* into supporting engagement with a pin 102 carried by support 80.

While my invention has been described as embodied in a welt-winding machine such as is claimed in my prior application, it is not the intention to limit its scope thereby, or otherwise than by the terms of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
